Fluke’s High Performance Insulation Tester
An insulation resistance tester is a tool used to measure the insulation resistance of various electrical components such as cables, transformer windings, motor windings, and so on. A MEG-OHM-METER is another name for it. Ohm’s Law is used to calculate insulation resistance. The insulation resistance value is indicated by the tester by injecting a known DC voltage in accordance with electrical standards and then measuring the current flowing. The result is provided in k ohm, M ohm, and G ohm.
The quality of the insulation resistance is determined by comparing this insulation resistance value to the accepted values from the standard. Each insulation resistance tester has three primary terminals: line, earth, and guard. The line terminal is connected to the conductor or winding under test, the earth terminal is connected to the equipment’s metal frame, which is normally earthed, and the guard terminal is used in special circumstances.
Faulty insulation is extremely hazardous to both electricians and people nearby; a bad insulation resistance tester is a dangerous (and costly) waste of time. A good insulation resistance tester, on the other hand, is simple to use, accurate, and has a wide insulation test range. Fluke is a well-known tester on the market, and you can rest assured that you’re getting one of the best insulation resistance testers available.
The Fluke 1507 insulation tester
The Fluke 1507 insulation tester is one of the best on the market, combining a mid-range price point with a variety of features that make it capable and user-friendly. This model can measure insulation resistance from 0.01 megaohm to 10 gigaohms. It can also work with a wide range of test voltages, starting with 50 V and gradually increasing to 100 V, 250 V, 500 V, and 1000 V. As an added safety feature, the Fluke 1507 will not allow you to conduct a test if the live circuit detection system detects a voltage greater than 30 V.
As an added precaution, the device discharges a capacitive voltage to reduce the possibility of the user being shocked. Another advantage is that the display is larger than on competing models. This improves visibility of your readings, and it’s also backlit, making it easier to work in the dark. While this insulation resistance tester is capable, it is also relatively compact and lightweight, so it will fit easily into your toolbox. With a weight of only 3.2 pounds, you can carry the Fluke 1507 around a jobsite all day without getting tired.
The Fluke 1507 has a longer battery life than other models in its price range. It should be able to perform around 1000 insulation tests with a brand new set of cells before they need to be replaced. This item comes with four AA batteries, which are required for it to function. With a Cat IV safety rating, you can be confident that this device is designed to work with higher voltages. This insulation resistance tester is one of the best for professionals due to its redundant safety features and accurate readings.
